Abstract: Maximum power point tracking (MPPT) of solar PV systems is vital under the variable solar radiation and panel as well as ambient temperatures. Various control algorithms are used in the standalone and grid-connected solar photovoltaic systems. Several MPPT controls have been investigated with sensors and sensor-less approaches. Tracking accuracy under shading conditions is essential to provide the constant power output of solar PV systems. Such controls should be economical for standalone and grid-connected PV systems. Recent advances in the control algorithms and methodologies for global MPPT and the future scope of such controls are discussed here.
